Opal Air - give it a miss
Opal air is still around as far as I know, up to last year anyway. Based in Coober Pedy. The pay is well below the award, you'll need a second job. and if you don't have 5 hours in a C172RG and C210 he'll charge you for it. If you don't have the time on the wages you'd get I worked out it it would take 100 hours of flying before you broke even! I don't think you'd be getting close to maxing your hours out there!
